Leveraging body-worn camera footage to assess the effects of training on officer communication during traffic stops.

Can training police officers on how to best interact with the public actually improve their interactions with community members? This has been a challenging question to answer. Interpersonal aspects of policing are consequential but largely invisible in administrative records commonly used for evaluation. In this study, we offer a solution: body-worn camera footage captures police-community interactions and how they might change as a function of training.

Escalated police stops of Black men are linguistically and psychologically distinct in their earliest moments.

Across the United States, police chiefs, city officials, and community leaders alike have highlighted the need to de-escalate police encounters with the public. This concern about escalation extends from encounters involving use of force to routine car stops, where Black drivers are disproportionately pulled over. Yet, despite the calls for action, we know little about the trajectory of police stops or how escalation unfolds.

Does "Jamal" receive a harsher sentence than "James"? First-name bias in the criminal sentencing of Black men.

Objective: Using archival and experimental methods, we tested the role that racial associations of first names play in criminal sentencing.

Hypotheses: We hypothesized that Black defendants with more stereotypically Black names (e.g.

Uncertain threat is associated with greater impulsive actions and neural dissimilarity to Black versus White faces.

Race is a social construct that contributes to group membership and heightens emotional arousal in intergroup contexts. Little is known about how emotional arousal, specifically uncertain threat, influences behavior and brain processes in response to race information. We investigated the effects of experimentally manipulated uncertain threat on impulsive actions to Black versus White faces in a community sample (n = 106) of Black and White adults.

Transition-Metal-Mediated Chemo- and Stereoselective Total Synthesis of (-)-Galanthamine.

An asymmetric synthetic route to (-)-galanthamine (), a pharmacologically active alkaloid used for the symptomatic treatment of early onset Alzheimer's disease, was successfully established with very high levels of stereocontrol. The key to achieving high chemo- and stereo-selectivity in this approach was the use of transition-metal-mediated reactions, namely, enyne ring-closing metathesis, Heck coupling, and titanium-based asymmetric allylation.

The thin blue waveform: Racial disparities in officer prosody undermine institutional trust in the police.

How do routine police encounters build or undermine community trust, and how might they contribute to racial gaps in citizen perceptions of the police? Procedural justice theory posits that officers' interpersonal communication toward the public plays a formative role, but experimental tests of this hypothesis have been constrained by the difficulties of measuring and manipulating this dimension of officer-citizen interactions. Officer-worn body camera recordings provide a novel means to overcome both of these challenges. Across five studies with laboratory and community samples, we use footage from traffic stops to examine how officers communicate to drivers and whether racial disparities in officers' communication erode institutional trust in the police.

Processing of Task-Irrelevant Race Information is Associated with Diminished Cognitive Control in Black and White Individuals.

The race of an individual is a salient physical feature that is rapidly processed by the brain and can bias our perceptions of others. How the race of others explicitly impacts our actions toward them during intergroup contexts is not well understood. In the current study, we examined how task-irrelevant race information influences cognitive control in a go/no-go task in a community sample of Black (n = 54) and White (n = 51) participants.

God as a White man: A psychological barrier to conceptualizing Black people and women as leadership worthy.

Neural adaptation to faces reveals racial outgroup homogeneity effects in early perception.

A hallmark of intergroup biases is the tendency to individuate members of one's own group but process members of other groups categorically. While the consequences of these biases for stereotyping and discrimination are well-documented, their early perceptual underpinnings remain less understood. Here, we investigated the neural mechanisms of this effect by testing whether high-level visual cortex is differentially tuned in its sensitivity to variation in own-race versus other-race faces.

Language from police body camera footage shows racial disparities in officer respect.

Using footage from body-worn cameras, we analyze the respectfulness of police officer language toward white and black community members during routine traffic stops. We develop computational linguistic methods that extract levels of respect automatically from transcripts, informed by a thin-slicing study of participant ratings of officer utterances. We find that officers speak with consistently less respect toward black versus white community members, even after controlling for the race of the officer, the severity of the infraction, the location of the stop, and the outcome of the stop.

Exploring the secrecy burden: secrets, preoccupation, and perceptual judgments.

Recent work suggests that secrecy is perceived as burdensome. A secrecy-burden relationship would have a number of consequences for cognitive, perceptual, social, and health psychology, but the reliability of these influences, and potential mechanisms that support such influences are unknown. Across 4 studies, the current work examines both the reliability of, and mechanisms that support, the influence of secrecy processes upon a judgment that varies with diminished resources (i.

trans-2-Tritylcyclohexanol as a chiral auxiliary in permanganate-mediated oxidative cyclization of 2-methylenehept-5-enoates: application to the synthesis of trans-(+)-linalool oxide.

The permanganate-mediated oxidative cyclization of a series of 2-methylenehept-5-eneoates bearing different chiral auxiliaries was investigated, leading to the discovery of trans-2-tritylcyclohexanol (TTC) as a highly effective chiral controller for the formation of the 2,5-substituted THF diol product with high diastereoselectivity (dr ∼97:3). Chiral resolution of (±)-TTC, prepared in one step from cyclohexene oxide, afforded (-)-(1S,2R)-TTC (er >99:1), which was applied to the synthesis of (+)-trans-(2S,5S)-linalool oxide.

Total synthesis of the tetracyclic lupin alkaloid (+)-allomatrine.

(+)-Allomatrine (1) has been synthesized using an imino-aldol reaction and N-acyliminium cyclization as key steps. Strategically, use of the tert-butylsulfinimine derivative of (E)-4-(trimethylsilyl)but-2-enal enabled the staged formation of three C-C bonds, a C-N bond, and the four stereogenic centers within the target.

Internalizing the closet: concealment heightens the cognitive distinction between public and private selves.

The present studies are the first in which social psychological methods were used to test the popular claim that the experience of concealing a stigmatized social identity leads to a "divided self." For people with concealable stigmas, concealment in public settings makes the public-private dimension of self-expression particularly salient, leading them to organize self-relevant information along this dimension. The result is a strengthened cognitive distinction between public and private aspects of the self, what we have termed public-private schematization.

Total synthesis of cis-sylvaticin.

An asymmetric total synthesis of (+)-cis-sylvaticin is described. Key steps include the use of permanganate-mediated oxidative cyclization of 1,5-dienes to synthesize the two major fragments 2 and 3 and a catalytically efficient tethered RCM to unite these THF-containing fragments. In addition, t-BuP 4 base was found to reliably promote rapid alkylation of the butenolide precursor fragment 4.

Stereocontrolled synthesis of (-)-galanthamine.

An enantioselective synthesis of (-)-galanthamine has been realized in 11 linear steps starting from isovanillin. A Mitsunobu aryl ether forming reaction was used to assemble the galanthamine backbone, which was stitched together using enyne ring-closing metathesis, Heck, and N-alkylation reactions affording the tetracyclic ring system. Control of relative and absolute stereochemistry was derived from an easily accessible enantiomerically enriched propargylic alcohol 13.

1-Aryl-3,4-dihydro-1H-quinolin-2-one derivatives, novel and selective norepinephrine reuptake inhibitors.

A novel series of 1-aryl-3,4-dihydro-1H-quinolin-2-ones have been discovered as potent and selective norepinephrine reuptake inhibitors. Efficient synthetic routes have been developed which allow for the multi-gram preparation of both final targets and advanced intermediates for SAR expansion.
